Os bacilos Gram-negativos não fermentativos são uma ameaça crescente para a saúde pública. Este estudo, realizado num hospital universitário no centro da Tunísia, forneceu um perfil epidemiológico e bacteriológico das estirpes isoladas entre 2019 e 2022. As principais espécies foram Pseudomonas aeruginosa (51,8%), Acinetobacter baumannii e Stenotrophomonas maltophilia, representando em conjunto 93,5% dos isolados. A resistência intrínseca da Pseudomonas aeruginosa e a sua capacidade de adquirir novos mecanismos de resistência ilustram a necessidade urgente de estratégias terapêuticas inovadoras. A evolução das estirpes deAcinetobacter baumannii e Stenotrophomonas maltophilia durante a pandemia de COVID-19 revela uma tendência preocupante. A utilização maciça de antibioticoterapia empírica está a favorecer o aparecimento de estirpes altamente resistentes, o que faz temer impasses terapêuticos. Por último, a ocorrência inesperada de infecções por Comamonas, nomeadamente de peritonite, sublinha a necessidade de uma vigilância acrescida face às espécies emergentes e ao seu impacto clínico nos doentes vulneráveis.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...
  • Advances in Flavivirus Research
    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

  • Brain Asymmetry of Structure and/or Function
    Lesley J. Rogers / Lesley JRogers
    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

  • The Epithelialto- Mesenchymal Transition ( EMT ) in Cancer
    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...

  • The Biology and Treatment of Myeloid Leukaemias
    There has been an observed decrease in the global mortality from cancer, mostly atributable to improved, particularly early, detection and prevention. For many carcinomas and leukaemias in adults, once the disease has reached a certain stage there are no therapies that are able to erradicate the cancer cells and cure patients. There has been progress in the treatment of acute m...
